About this part

Product Details

When you're rebuilding the heart of your engine, the piston wrist pins are critical for connecting the piston to the connecting rod. This set from Manley Performance is built with 9310 steel, a strong material known for its durability under high stress, making it a solid choice for performance builds or when you need to replace worn components.

These wrist pins measure 22.5mm in diameter with a 2.250 inch length and a .250 inch wall thickness. The precise sizing ensures a proper fit within the piston and connecting rod, which is essential for smooth operation and longevity. Because they are made from 9310 steel, they offer good resistance to fatigue and wear, helping to ensure your engine's internal components hold up under demanding conditions.

This set includes four wrist pins, suitable for a typical four-cylinder engine build or for replacing all the pins in a V-twin motorcycle. Remember that these are not CARB approved and cannot be shipped to California. Always refer to your engine's service manual for specific installation procedures and torque specifications.
